Yu Ruhai sent Mu Yan to the carriage in the courtyard, and watched the carriage leave with a friendly smile, before pulling the slightly stiff skin and turning around to find Yu Jiao.

Yu Jiao washed the medicine mill and spatula in the stove room, after all, it was stained with sheep dung, but she still had to wash it cleanly, so as not to feel embarrassed when she used it again.

Yu Ruhai leaned out at the door of the stove room and asked Yu Jiao, "In five days, can the Mu family's illness be cured?" ”

Yu Jiao's face was a little impatient, this old man asked for verification over and over again, and he was not tired, but he tried to be down-to-earth, but Yu Jiao still felt tired when she responded.

"Some words are said many times, and they all mean the same thing, and you don't have to ask again and again." Yu Jiao wiped the cleaned medicine mill with a rag and put it on the stove.

Yu Ruhai was bored, but he was going to use Yu Jiao right now, where did he compare these, his face did not change, and he continued, "Meng Yatou, what kind of medicinal powder did you put on Uncle Nianjiu's back?" I don't know when you made it. ”

Yu Ruhai wanted to ask for a recipe, and Yu Jiao knew it, but this was a recipe handed down from ancient times, and she had nothing to hide.

"Jingyue Quanshu" has a record, with a crucian carp, cut off the intestines, sheep dung in it, baked black, for fine powder, dry mixed with scabies on the back, sores are collected, but no harm."

Yu Ruhai listened to what Yu Jiao said, and said with some emotion and curiosity, "There is such a miraculous effect?" "Jingyue Quanshu" is a medical book? Which healer is mighty? I've never heard of it. ”

Yu Jiao was urged by her grandfather since she was a child, familiar with all kinds of medical books and pharmacopoeia, and all the ancient and modern celebrity doctors related to medical skills are like a few treasures, know very well, and explain effortlessly, "A doctor named Zhang Jiebin, the word Jingyue, has passed away, and the "Jingyue Quanshu" he left behind is indeed worth seeing. ”

Yu Ruhai was very moved after hearing this, if he could get such a good medical book, wouldn't he be able to gain a lot of medical skills, "Meng Yatou, do you have this medical book at home?"

Yu Jiao poured out the water from the pot and sneered, "I don't have it at home, I followed the master when I was a child, and I just saw it." ”

Yu Ruhai still didn't give up, and asked, "Then can you be silent?" ”

"I can't." Yu Jiao rolled her eyes in her heart, this old man of the Yu family really dared to think about it.

Yu Ruhai was disappointed, turned around and left the stove room, returned to the herb room and wrote down the medicine used by Yu Jiao to treat back gangrene in detail, and sandwiched it in the medical book again, just five days later, to see the effect of the treatment of back gangrene, if Uncle Mu Nianjiu's disease is cured, then this prescription for treating gangrene alone is enough for the Yu family to become famous.

Yu Jiao cleaned up the stove room, went back to the east house, and looked for Yu Qizhen to practice calligraphy.

It's just that Yu Qiyu is surprisingly cold today, although he usually doesn't like to talk to Yu Jiao very much, but today since Yu Jiao entered the door and sat down next to the bookcase, he didn't say a word.

When Yu Jiao practiced calligraphy before, the pen, ink, paper, and inkstone were all ready, but now the inkstone is dry, Yu Jiao had to support herself, picked up the ink block, mixed a little water into the inkstone, and raised her eyes to see Yu Qiyu's face while grinding.

Yu Qiyu was still sitting on the bed, holding a book of scriptures in his hand, looking at it with his eyes down.
